Campanula plant named ‘Chico Blanco’

ABSTRACT

A new and distinct  Campanula  plant named ‘Chico Blanco’, characterized by its compact and broadly upright plant habit; basal branching habit; freely flowering habit; white-colored flowers; and long flowering period.

Botanical designation: Campanula glomerata.

Cultivar denomination: ‘CHICO BLANCO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Campanula plant, botanically known as Campanula glomerata and hereinafter referred to by the cultivar name ‘Chico Blanco’.

The new Campanula plant is a product of a planned breeding program conducted by the Inventor in Oude-Wetering, The Netherlands. The objective of the breeding program is to create new freely-flowering Campanula plants that flower for a long period of time.

The new Campanula plant originated from an open-pollination during the summer of 2006 of an unnamed selection of Campanula glomerata, not patented, as the female, or seed, parent with an unknown selection of Campanula glomerata, as the male, or pollen, parent. The new Campanula plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled environment in Oude-Wetering, The Netherlands during the summer of 2007.

Asexual reproduction of the new Campanula plant by divisions a controlled environment in Oude-Wetering, The Netherlands, since August, 2009, has shown that the unique features of the new Campanula plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Campanula plant have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Chico Blanco’. These characteristics in combination distinguish ‘Chico Blanco’ as a new and distinct Campanula plant:

-   -   1. Compact and broadly upright plant habit.     -   2. Basal branching habit.     -   3. Freely flowering habit.     -   4. White-colored flowers.     -   5. Long flowering period.

Plants of the new Campanula differ from plants of the female parent selection primarily in plant size and flower color.

Plants of the new Campanula can be compared to plants of Campanula ‘Alba’, not patented. In side-by-side comparisons conducted by the Inventor in Oude-Wetering, The Netherlands, plants of the new Campanula differed primarily from plants of ‘Alba’ in the following characteristics:

-   -   1. Plants of the new Campanula were more compact than plants of         ‘Alba’.     -   2. Plants of the new Campanula were more freely flowering than         plants of ‘Alba’.     -   3. Plants of the new Campanula and ‘Alba’ differed slightly in         flower color.

Plants of the new Campanula can also be compared to plants of Campanula ‘Anoeska’, not patented. In side-by-side comparisons conducted by the Inventor in Oude-Wetering, The Netherlands, plants of the new Campanula differed primarily from plants of ‘Anoeska’ in the following characteristics:

-   -   1. Plants of the new Campanula were more compact than plants of         ‘Anoeska’.     -   2. Plants of the new Campanula were more freely flowering than         plants of ‘Anoeska’.     -   3. Plants of the new Campanula and ‘Anoeska’ differed in flower         color as plants of ‘Anoeska’ had blue-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Campanula plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Campanula plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Chico Blanco’ grown in a container.

The photograph on the second sheet is a close-up view of a flowering stem of ‘Chico Blanco’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown in 18-cm containers during the spring and early summer in a glass-covered greenhouse in Oude-Wetering, The Netherlands and under cultural practices typical of commercial Campanula production. During the production of the plants, day temperatures ranged from 15° C. to 25° C. and night temperatures ranged from 5° C. to 16° C. Plants were 18 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
